# Convert a character string into a random seed

### Description

This function creates a seed for the random number generator from a character string. Character strings can be based on student names so that every student has a different random sample, but the teacher can generate the same datasets.

### Usage

1 |

### Arguments

`x` |
A character string |

`set` |
Logical, should the seed be set or just returned |

`...` |
Additional parameters passed on to |

### Details

Simulations or other situations call for the need to have repeatable random numbers, it is easier to remember a word or string than a number, so this function converts words or character strings to an integer and optionally sets the seed based on this.

Teachers can assign students to generate a random dataset using their name to seed the rng, this way each student will have a different dataset, but the teacher can generate the same set of data to check values.

Any characters other than letters (a-zA-Z) or digits (0-9) will be silently removed. This function is not case sensitive, so "ABC" and "abc" will generate the same seed.

This is a many to one function, so it is possible to find different words that generate the same seed, but this is unlikely by chance alone.

### Value

This returns an integer (but mode numeric) to use as a seed for the
RNG. If `set`

is true then it is returned invisibly.
